The student, Bryan Davis, told police that he was walking to a friend's apartment Wednesday on West Campus when the balloon hit him in the leg near University Towers at 23rd and Pearl streets.

Bryan, who is black, told the Burnt Orange Report that the shock took hours to wear off. "I don't feel safe walking around West Campus myself anymore," he told the publication.

The attack comes on the heels of similar incidents last October, when several minority students told Austin police that they were hit by bleach-filled balloons in West Campus apartment complexes. The attacks sparked a march through West Campus that made national headlines.

The investigation into the attacks last year was suspended due to lack of evidence, said Corporal David Boyd of the Austin Police Department.

Boyd said that an APD detective is being assigned investigate the Aug. 21 case.

Gregory J. Vincent, vice president for diversity and community engagement at UT-Austin, said the university takes the report seriously.

"The University of Texas at Austin has long been committed to promoting diversity and ensuring respect and inclusion throughout the campus community," Vincent stated in a press release. "Our university should be a haven and home to students of all backgrounds."

University police will work closely with Austin PD on the investigation, he stated.

"The Dean of Students and our campus climate response team, which coordinates the university's response to bias incidents, are actively reviewing these allegations and are also prepared to work with Austin Police on their investigation," Vincent said in the statement.

Boyd, of Austin PD, urged anyone with information about the cases to come forward.

"If there's anybody in the public that has had similar things happen to them, we want them to come forward and let us know about it," he said.
